An outputting apparatus comprises: a changing circuit to change a bit map font in accordance with a resolution of an outputting mechanism in the case where a resolution of the bit map font to be generated differs from the resolution of the outputting mechanism; a developing circuit to develop dot pattern information of the bit map font changed by the changing circuit; and an outputting device to output the dot pattern information developed by the developing means. The changing circuit executes a smoothing process by interpolating one dot into a zigzag portion of a character pattern. The bit map font is a down-load font.
